Hello to all - I’m new here and been slowly upgrading my theater system. Latest purchases include a Denon AVR-3700H, an SVS Prime center channel, and an LG 65” OLED. I’m running a 7.2.2 configuration at present. Most of the remainder of the equipment are hand-me-downs from my dedicated audio system — which leads to my question.\n\nSince my speakers are not identical across the channels, being from several different manufacturers (Thiel, B&W, SVS) does system level balancing at 75db really hold when actually listening at other than 75db? Fortunately, all these speakers have similar sensitivity at about 86db\/w, but that would not seem to guarantee that their db per watt slopes would be the same.\n\nSo, is this an issue? The Denon does seem to have the ability to store up to 4 “favorites” presets which could include speaker level trims for different volume levels.\n\nAny guidance would be greatly appreciated!
